Not into right or wrong but I have reset the springs for a number of S1 over the past years and have found no difference between hot or cold (except burnt hands) before set or after. All I do is bend them to the shape I want with a press over a sort distance of the spring one leaf at a time. Slightly more as you work down the pack. The press or pipe bender is a lot easier than a hammer.
Go a little more than spec but not to much.
When old narrow thin 80"springs are involved, I take a good thick long leaf say off the back of a long wheelbase and cut down to size to replace 2 of the thin leaves this makes the old pack stand up nice.
